ACETYLENE GAS GENERATOR.

SPECIFICATION forming party of Letters Patent No. 679,315, dated July 30, 1901.

Application filed October 20, 1900- Serial No. 33,750- (No model.)

To all whom it may concern.-

Be it known that we, BoHUMIL HoLUB, constructor, and PANKRAo DVORACEK, engineer, both of Vinohrady-Prague, Bohemia, Austrian Empire, have invented a certain new and useful Improvement in Acetylene-Gas Producers, of which the following is a specification.

Our invention relates to the improvement of acetylene-gas producers, and has particular relation to the class of such producers which are automatic and without gasometer.

The object of our invention is to provide a cheap, economical, self-regulating, and compact acetylene gas producer which offers complete surety against explosions and can be set to work at any time without any preparation. The said object we accomplish in the manner illustrated in the accompanying drawings, in Which Figures 1, 2, and 3 show the apparatus in three views. Figs. 4 and 5 show the waterrose in an axial section and in a horizontal view. Figs. 6 and 7 show the starting and stopping key in two views. Figs. 8 and 9 show the middle part of the apparatus in two vertical sections through its axis. Fig. 10 is a side view of Fig. 9. Fig. 11 is the regulator of the Water-flow in an axial section.

Similar numerals refer to similar parts throughout the several views.

As will be seen, the apparatus is arranged in the shape of a column, which, if needed, is surmounted by a oarbid-mill. This is the case only if carbid is used in pieces, while if granulated or pulverized car-bid is used no mill-will be needed at all. The upper part of the column is on its top closed by a tight lid, closing the opening by which the carbidreservoir is filled. The bottom of this reservoir has the shape of a funnel. At the lower part of it rotates a horizontal feeding-worm 2, which transports the carbid from the bo tom of the reservoir 1 through the opening 31, from where it falls down into the acetylone-reservoir 8. The feeding-worm transports the nearest parts of the disintegrated carbid from the bottom of the funnel, in which itwould soon form a cavity and a kind of vault, which would keep the rest of the carbid from falling down. For the purpose of preventing this irregularity in the feeding a toothed wheel-disk 1 is used, which is lo cated in the inclined wall of the bottom funnel, gearing with the worm 2, so that it is turned continually as long as the feeding goes on, and by this means brings down the granulated or pulverized material, which otherwise might accumulate above the feedingworm without falling down.

The acetylene-reservoir 3, which forms the lower part of the column, is open on its bottom and immersed in water, which stands in a vessel 6 up to a constant level, having its runner or Waste-pipe at 5. Fresh water runs into the acetylene-reservoir through a rose 10, which is situated in the middle and above the water-level and is arranged so as to send its spray upon the carbid just while it falls from the feeding-worm into the water. The acetylene gas flows through pipe 8 directly to the flames or through a cleaning apparatus, as the case may be. The spray from. the rose 10 washes 0d the dust over and the scum upon the water-level inside the reservoir 3. It cools at the same time the acetylene gas sufficiently, so that in most cases it can be used without any further process. Afloat 9 swims upon the water inside the reservoir 3, and it has a lever, the fulcrum of which is at 11,

outside the reservoir 3, the fulcrum being situated in the water which surrounds it. A suitable slot is formed in the Wall of the reservoir for the passage of the lever just mentioned. The movements of the float 9 are transmitted in a diminished degree by means of rod 12, a cross-piece 12, the arms 12, a cross-head 21 22, and a rod 14 to a valve 13, which opens more or less a passage 15 for the feeding-water, which runs through the tube 16 into a cylinder 18, traversing the passage 15 and flowing afterward through pipe 17 into the Water-motor A, and from this through tube 19 and the rose 10 to the carbid in the acetylene-reservoir 3. The valve-rod 14. is

threaded on its upper end, and the exact position of valve 13 can be regulated by means of a nut 36, a spiral spring 20 being interposed between the nut 36 and the part 22 of the cross-head to press the nut against the part 21, and thus put it under restraint.

It is by no means necessary that the feeding-screw must be rotated by a water-motor. In fact, any other small motor, weight, clockwork, or the like can perform the same work, being regulated as to speed or power through the float Any known checking arrangement can be used.

lf the production of the acetylene gas increases in the reservoir 3, the water-level will be depressed, the float 9 falls, and the valve 13 begins to obstruct the passage 15. Therefore less water is admitted into the motor and also into the rose 10. The consequence of it will be a slower feeding of carbid and slower feeding of water. Therefore less acetylene will be produced, its pressure in the reservoir 3 will diminish, and the .Water in this reservoir will mount and with it also the float 9.

If the nut 36 is well regulated, there will be a regular production of acetylene however the number of flames may change. The apparatus regulates itself automatically.

The orifice 31 can be closed by a stopper 32,

which is fitted to the spindle 33 of the feeding-worm 2. This spindle is prolonged into the box 23 of the motor, and it can be displaced in the direction of its own axis notwithstanding the fact that it bears in one of the wheels 37, which transmits the rotation to the spindle 33. In our example this may be done so that the end of the spindle is square, and it is fitted into a square central hole of the toothed wheel of the motor. The other end of the spindle is guided by a piston 34 in the wall of the reservoir, and it is provided with a head 29, which turns freely in a sliding box 35. From the opposite side and in the prolongation of the spindle 33 is a spindle 27, led through the wall of the reservoir. This spindle 27 can be turned in either direction by means of a handle 28; but it is arranged so as not to advance in the direction of its axis. Spindle 27 is threaded on its inner end,

and it is screwed into the sliding block 35.

Turning it by the handle 28 in one or the 0pposite direction will therefore effect a displacement of the stopper 32 in the direction of the axis, and therefore opens or closes the outlet 31 of the carbid. If the motor runs when this opening is shut, or partly so, the right end of the spindle will slide through the toothed Wheel 37 without afiecting in any way the working of the motor.

It will be understood that if one lets the motor run and opens the carbid-opening by turning the handle 28 carbid will be fed and fall from the carbid-reservoir 1 into the water in the reservoir 3, being washed and wetted through on its way from 31 to the water by the spray which falls from the rose 10. Therefore acetylene gas is produced and flows through pipe 8 to the flames. If the production is stronger than the consumption, the quantity of gas in the reservoir 3 will increase and so will its density. The float 9 will fall with the level of water in 3, while the level in 6 will remain unchanged. This will cause the valve 13 to partially close its opening 15, and therefore less water will flow through the rose 10, and the movement of the motor and of the feeding-worm will get slower, and less carbid will fall down from 31. The production will begin to diminish, and the level in 3 will mount. In this way the apparatus will regulate itself automatically. If the number of lighted jets is changed or their flames Varied, the regulation will begin and will reestablish the regularity of the flames in an instant, the gas being produced only in the quantity exactly needed. Should this not be the case, then it will suffice to turn slightly the nut 36, so as to open or shut the opening 15 more or less, and the perfect regularity of the work will soon be reestablished.

The carbid-mud from the used-up carbid falls into an open vessel 7, which is put under the apparatus in the reservoir 6 and can be replaced by a fresh one and emptied at any time.

It will be understood that this apparatus, which needs no gasometer, can be filled with carbid without any interruption, and though it is comparatively small and cheap it works with perfect accuracy and without any danger, having no accumulation of acetylene gas, which is produced automatically in the I same ratio as it is being used, and needs quite Y a minimum tension only, the height of its there is Water and carbid in it, if the motor is i the handle 28.

water-head being limited by the length of immersion of the apparatus in the vessel 6. The apparatus needs no preparation for its use. In fact it works at once, as soon as loosened and the stopper 32 opened in turning It does not matter whether I only one flame or a considerable number of The apparatus regulates itself quite automatically I in a moment, and never any interruption in the regularity of action is felt.

Having now fully described our invention,
